Question 9 (1 point) A falling 2-kg mass of putty D has a downward velocity of 10 m/s just before it strikes the uniform 10-kg plank ABC. The putty remains attached to the plank in the location shown following their initial contact. The size of the putty is negligible and the plank is initially at rest in a horizontal configuration (prior to contact with the putty). The thickness of the plank is also negligible with regards to its length. What is the angular velocity of the putty/plank assembly at the instant that immediately follows the impact? D 300 mm B А с 9 800 mm 400 mm
